A Note on Hosting Selection

While TTFB and performance metrics are important indicators, choosing the right hosting provider involves many other factors: security measures, customer support quality, uptime guarantees, scalability options, and pricing structure. Academic research emphasizes that a balanced approach considering all these aspects leads to better long-term outcomes.
